I am using a GroupingCollection to bind my advanceddatagrid. I have used groupingcollection to group the data by date.
Now I need to select the data in the datagrid through the code. Does anyone have any idea as to how to do this? I need to loop through the adg's dataprovider and select the item that matches the criteria for the selection.
Please advise
Thanks :)
Okay, depending on how the question in interpreted, this code will find the items that match the grouping year that is selected. I added a click=findStuff(event)
to the mx:AdvancedDataGrid
, as shown here:
[Bindable]
public var myData:ArrayCollection = new ArrayCollection([
{name:'Denise', grad:'2000'},
{name:'Steph', grad:'1990'},
{name:'Jane', grad:'2000'},
{name:'Nicole', grad:'2000'},
{name:'Donna', grad:'1990'}]);
public function findStuff(e:Event):void {
var groupColl:GroupingCollection = adGrid.dataProvider.source;
var items:Object = groupColl.source;
var ac:ArrayCollection = new ArrayCollection();
for (var i:int=0; i<items.length; i++) {
if (items[i].grad == e.target.text) {
ac.addItem(items[i].name);
}
}
Alert.show("selected items: " + ac.toArray());
}
<mx:GroupingCollection id="coll" source="{myData}">
<mx:Grouping>
<mx:GroupingField name="grad" />
</mx:Grouping>
</mx:GroupingCollection>
<mx:AdvancedDataGrid id="adGrid" dataProvider="{coll}"
click="findStuff(event)"
initialize="coll.refresh()">
<mx:columns>
<mx:AdvancedDataGridColumn headerText="name" dataField="name"/>
</mx:columns>
</mx:AdvancedDataGrid>
Note that first I get the GroupingCollection from the AdvancedDataGrid dataProvider, then I get the items from the GroupingCollection. These could be combined into one step, but this way is more readable for the example. Not knowing exactly what data you're looking for I just grab the name
field from the data item
but there's no reason you couldn't grab the whole item
.
Hopefully this is a step in the right direction for you.
